To all whom it may concern:

Be it known that l, J AN BJnLIs, a subject of the King of Hungary,residing at East Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Collision-Preventers, ofwhich the following is a specification.

This invention relates to new and useful improvements in collisionpreventers.

The primary obj ect of the invention is the provision of an attachmentfor boats whereby the motive power thereof will lbe automaticallyreversed in the event that the vessel approaches sufficiently near toany object to engage the projecting portion of the device therewith.

A further obj ect of the invention is to provide a bow carried fenderupon a boat, any violent contacting of which automatically reverses theboat propelling means whereby the boat is reversed in its direction oftravel preventing injurious collisions.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application and in which likedesignating 'characters refer to corresponding parts throughout theseveral views: Figure 1 1s a side elevation of a Jforward portion of avessel provided with the present device, the engine and its controllingmeans being illustrated by dotted lines. Fig. 2 is a top plan viewthereof. Fig. 3 is an enlarged side elevational view of the device,parts being broken away, and Fig. 4l is a lonvitudinal sectional viewtaken upon line 11F-IV of Fig. 3.

The present device is herein illustrated in connection with a boat 10having a propelling engine or motor 11 'positioned therein, the`vertically arranged mast said boat having a 13 at the bow portion 12upon the deck thereof.

A bracket 14 is secured to the prow 15 of the boat at a point adjacentthe deck 13 and is provided with forwardly extending tubular shockabsorber cylinders 16 pivoted to the said bracket as at 17 andcontaining buffeting coil springs 18 bearing against pistons 19 arrangedwithin the said cylinders and provided with rods 20 pivotally connectedto said pistons. j

Upright rectangular frames 21 provided with parallel vertical pickets223in the form of fence sections are secured together at their forwardedges in angular arrangement having their upper rear corners connectedtogether by a brace 23. The piston rod 20 of the upper shock absorber isconnected at its forward end to the brace 23 and also within the forwardangular portion 24 of the frames 21, while the piston rod 20 of thelower shock absorber extends forwardly and is attached as at 25 to theangular connecting point at the bottom o-f the frames 21. The said lowershock absorber piston rod 20 is obliquely arranged while oblique struts26 connect the said lower piston rod 20 with the lower rear corners ofthe frames 21.

A trip bar 27 extends inwardly of the boat 10 through the prow thereofas at 28 having its inner free end 29 slightly spaced from a reversinglever 30 of the motor 11 whereby upon an inward longitudinal shifting ofthe bar 27 the end 29 thereof engages the lever 30 for reversing thesaid motor thereby causing the boat 10 to stop its forlward travel andbe propelled rearwardly.

The forward end of the bar 27 is secured to a lower brace 31 connectingthe lower rear corners of the frames 21, the bar 27 extendingtransversely of the said brace 31 and secured to the lower forwardmeeting corners of the frames 21 at the aforementioned point 25 thereof.v

.From this detailed description of the device, at once apparent, itbeing understood that during the forward movement of the boat 10, theforwardly positioned buii'er formed by the frames 21 and pickets 22 willcome in contact with any object in advance of the boat, which contactwill be only slightly felt by the boat 10, the shock thereof beingpartially absorbed by the shock absorber springs 18. The rearwardmovement of the frames 21 longitudinally slides the bar 27 rearwardlyeecting a reversal of the motor 11 as heretofore described producing abacking movement of the boat`10, thus preventing any collision objectpositioned forwardly thereof. .Guy

klines 32 connect the forward and rear cor- 21 with a point adjacent 12as at 33 while a horiners of the frames the top of the mast the completeoperation thereof will be' between the boat 10 and any l v zontal stayrope 34: may be provided for the said mast if found desirable.

While the form of the invention herein shown and described is what isbelieved to be the preferable embodiment thereof, it is nevertheless tobe understood that minor changes may be made in the form, proportion anddetails of construction without departing from the spirit and scope ofthe invention as hereinafter claimed. Y

What I claim as new is r- In an automatic reversing device for ships,the combination with a ships engines reversing lever, of operating meansfor said reversing lever comprising a bracket attached to a ships bow, apair of forwardly- .extending cylinders pivoted at their rear Copesofthis patent may be obtained for ve cents each, byraddressing theCommissioner of Patents, Washington, D.
